Adam Curtis, documentarian and film collage expert, has a small film festival at, aptly enough, Whitechapel Art Gallery this coming Saturday and Sunday. They're showing episodes from Pandora's Box, The Century of the Self, The Power of Nightmares, and The Trap. He'll also be hosting a couple of talks about some of his ideas. You can find some of these shows on torrent sites (I think Chomsky Torrents have a few), but if you're in London on those days and can get tickets, you should. It's not like they're ever going to get released on DVD; those clips will be hellishly difficult to get cleared by copyright lawyers.
